BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a multi-functional window washing and wiping device, and particularly to a window washing device which may achieve the purpose of washing glass windows in buildings without the risk of having window washers hang in mid-air.

2. Description of Related Art

Because glass technology is advanced, and because glass has high penetrability, and is sparkling, clean, beautiful and modern, it is well suited for exterior walls or glass shutters in buildings. After long-term exposure to wind and rain, however, glass windows may easily get soiled with grime and water stains, which may affect the outward appearance of buildings as well as city appearance. Therefore, glass windows need regular washing and maintenance. Currently, glass exterior walls or glass windows are manually cleaned in most cases. Personnel access exterior walls of a building by hanging on a platform and wash the walls on the moving platform. This existing method of window washing is highly risky because it is performed in mid-air and the platform is shaky. This is not an easy job for everyone, and therefore there is often a shortage of manpower. It is impossible for inhabitants to clean their own windows, either. In view of the foregoing, after laborious research and experiments, the applicant of the present invention has devised a multi-functional window washing and wiping device which may reduce the risk of having window washers hang in mid-air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer both to FIG. 1 and FIG. 2, as well as FIG. 3, showing a three-dimensional view, a three-dimensional exploded view, and a view of a transmission structure according to the present invention. As the figures show, a multi-functional window washing and wiping device according to the present invention comprises a device body 1 and a retractable rod 2 connected to the device body 1, wherein on a rear rim of the device body I is disposed a protruding ear 11 for pivotally connecting the device body 1 to the retractable rod 2. In an interior of the device body 1 is disposed a toothed gear assembly 3 comprising a plurality of toothed gears. In the present embodiment, the toothed gear assembly 3 comprises at least a transmission gear 31, two driven gears 32 meshed with the transmission gear 31, and two rotating discs 33 fixedly disposed on the two driven gears 32. Through holes going through a top of the device body 1 are respectively disposed at centers of the two driven gears 32 and two rotating discs 3 to be respectively connected with tube bodies 34 and 35 for allowing a cleaning tool 4 such as a brush, a sponge or a piece of cloth to be disposed on the two rotating discs 3 (fixed by attaching two hood-and-loop fasteners to each other).

The transmission gear 31 of the toothed gear assembly 3 is meshed with a vortex rod 36. Wheels 37 are pivotally connected on two ends of the vortex rod 36 respectively, protruding and exposed on two sides of the device body 1. When moving the device body 1 to rotate the wheels 37, the vortex rod 36 is driven to drive the entire toothed gear assembly 3 so that the cleaning tool 4 disposed on the two rotating discs 33 is rotated. Above the device body 1 is further disposed a motor 38 and a transferring member 381. By the rotating and switching of the transferring member 381, a transmission shaft of the motor 38 is pivotally connected with the transmission gear 31, which is disengaged from the vortex rod 36; or by the rotating and switching of the transferring member 381, the transmission gear 31 is meshed with the vortex rod 36 and the transmission shaft of the motor 38 is disengaged from the transmission gear 31.

A bottom end of the retractable rod 2 is pivotally connected to the protruding ear 11 disposed on the device body 1, so that the retractable rod 2 may swing at elevated and depressed angles. A handle 21 is disposed at a top end of the retractable rod 2. The tube bodies 34 and 35 disposed above the device body 1 are properly fixed to the retractable rod 2 and are pulled out along the retractable rod 2 for connecting to detergent and water.

A multi-functional window washing and wiping device is formed by assembling the foregoing components. When using the device, assemble a cleaning tool 4 such as a brush, a sponge, or a piece of cloth on the toothed gear assembly 3; input detergent and water via the tube bodies 34 and 35 and release the detergent and water through the cleaning tool 4 below the device body 1; and hold the retractable rod 2, place the device body 1 on a glass window, and move the device body 1 along the glass window. The purpose of washing glass windows in buildings is achieved by rolling the cleaning tool 4 by driving the toothed gear assembly 3 via wheels 37 without the risk of having window washers hang in mid-air. It will be appreciated that the present invention may also be used for cleaning floor. In a similar manner, various cleaning tools 4 may be disposed below the device body 1 and floor cleaning is performed by a user holding the handle 21.

Please refer to FIG. 4, showing a view of the present invention in operation. Please also refer to FIGS. 1 and 2. As the figures show, when using the present invention, the user holds the retractable rod 2, places the device body 1 on a glass window, and moves the device body 1 along the glass window. The rotation of the wheels 37 drives the toothed gear assembly 3, which drives the cleaning tool 4 to rotate. When the wheels 37 rotate, the vortex rod 36 drives the transmission gear 31, which drives the two driven gears 32 respectively. The two driven gears 32 then respectively drive the two rotating discs 33, which drive the cleaning tool 4 disposed on the two rotating discs 33. Detergent and water are released via the tube bodies 34 and 35 to achieve the purpose of washing glass or cleaning floor. Considering that detergent may cause the wheels 37 to slide when cleaning glass, according to the present invention, by the rotating and switching of the transferring member 381, a transmission shaft of the motor 38 is pivotally connected with the transmission gear 31, which is disengaged from the vortex rod 36. As such, the transmission gear 31 is transmitted by the motor 38 so as to maintain the best cleaning effect.

Please refer to FIG. 5, showing a view of another preferred embodiment in use according to the present invention. As the figure shows, the present invention may further be provided with a gripper 5, which may turn about freely. A buckle part 51 is disposed on the gripper 5, and at least two locking members 52 are disposed at appropriate positions on the gripper 5. When using the present invention, fix the gripper 5 on a window frame 6 with the locking members 52 and place and position the retractable rod 2 across the buckle part 51, so that the entire window washing device may be pulled forward and backward and may swing upward and downward with the buckle part 51 as a pivot, which makes it easier and effort-saving to clean glass.
